FIG. 9 is an example of a display screen where the information processing apparatus according to the same embodiment displays selection items in a step-by-step manner.

First, FIG. 1 illustrates an example of an information processing apparatus 100 to which the technology of the present specification is applied. The information processing apparatus 100 is a terminal apparatus that has a function of detecting a tilt of a casing. For example, the information processing apparatus 100 may be a terminal apparatus such as a portable phone, a portable music play apparatus, a portable image processing apparatus, a portable game console, a tablet-type terminal, a Personal Computer (PC), or the like.

The information processing apparatus 100 includes a display unit 107 on a surface of its casing. A touch sensor may be overlapped with the display unit 107 to detect a position of an operation body on a display screen displayed on the display unit 107. Also, in the present specification and the drawings, the longitudinal direction of the casing of the information processing apparatus 100 is defined as a y direction (example of a first direction), and the lateral direction of the casing is defined as an x direction (example of a second direction).

Referring to FIG. 2, a functional configuration of an information processing apparatus 100 a according to the first embodiment of the present disclosure is illustrated. Also, in the present specification and drawings, a plurality of elements having substantially the same functional configuration may be distinguished by different alphabets attached after the same reference sign. For example, a plurality of elements having substantially the same functional configuration, if necessary, are distinguished like an information processing apparatus 100 a and an information processing apparatus 100 b. However, if each of a plurality of elements having substantially the same functional configuration need not be especially distinguished, only the same reference sign is assigned thereto. For example, if an information processing apparatus 100 a, an information processing apparatus 100 b, and the like, need not be especially distinguished, the information processing apparatuses are simply referred to as information processing apparatuses 100.

The information processing apparatus 100 a mainly includes a tilt detecting unit 101, an operation body detecting unit 103, a control unit 105, a display unit 107, and a communication unit 109.

(Tilt Detecting Unit)

The tilt detecting unit 101 has a function of detecting a tilt of the casing of the information processing apparatus 100. The tilt detecting unit 101 may be, for example, a motion sensor such as an angular velocity sensor, an acceleration sensor, an angle sensor, or the like. Also, the tilt detecting unit 101 may be realized by a combination of at least two or more of the above motion sensors. An example of the angular velocity sensor used herein may be a vibration-type gyro sensor, a rotation coma gyro sensor, or the like. Also, the acceleration sensor used herein may be, for example, a piezoresistive acceleration sensor, a piezoelectric acceleration sensor, a capacitive acceleration sensor, or the like. Also, an example of the angle sensor may be a geomagnetic sensor. Also, it may be preferable that the motion sensor used as the tilt detecting unit 101 is a sensor capable of detecting a rotation angle with respect to three axes. The tilt detecting unit 101 may provide information about a detected tilt to the control unit 105.

(Operation Body Detecting Unit)

The operation body detecting unit 103 has a function of detecting an operation by an operation body. The operation body detecting unit 103 may be, for example, realized by a touch sensor that is installed overlappingly on the display unit 107 to detect a position of an operation body with respect to a display screen displayed on the display unit 107. The operation body may be, for example, a user's finger or a stylus pen. The operation body detecting unit 103 may provide information about an operation by a detected operation body to the control unit 105.

(Control Unit)

The control unit 105 a has a function of controlling an overall operation of the information processing apparatus 100 a. For example, the control unit 105 a may control an operation of the information processing apparatus 100 a based on at least one of information about a tilt detected by the tilt detecting unit 101 and information about an operation by an operation body detected by the operation body detecting unit 103. Also, the control unit 105 a may control a display of a display screen displayed on the display unit 107, based on at least one of information about a tilt detected by the tilt detecting unit 101 and information about an operation by an operation body detected by the operation body detecting unit 103. Also, the control unit 105 a may control a connection of an external apparatus through the communication unit 109.

For example, a description will be given of control of the control unit 105 of the information processing unit 100 in a case where selection items for determining an operation of the information processing apparatus 100 a are of a layered structure as illustrated in FIG. 3. The control unit 105 may select a selection item of a layered structure, based on an operation of a plurality of steps using a tilt detected by the tilt detecting unit 101. For example, assume a case where selection items of a first layer include a selection item 1 and a selection item 2, and selection items of a second layer lower than the first layer include a selection item 1-1, a selection item 1-2, a selection item 1-3, and a selection item 1-4. For example, the control unit 105 may first select any one of the selection item 1 and the selection item 2 based on a tilt operation using a tilt with respect to a y direction of the casing. Herein, the y direction is an example of a first direction, and the tilt operation is an example of a first operation using a tilt with respect to the first direction. Also, if any selection item is selected from the first layer and thereafter a selection item of the lower layer of the selected selection item is present, then the control unit 105 may select any one of the selection item 1-1, the selection item 1-2, the selection item 1-3, and the selection item 1-4 based on a swing operation using a tilt with respect to an x direction of the casing. Also, herein, the x direction is an example of a second direction perpendicular to the first direction, and the swing operation is an example of a second operation using a tilt with respect to the second direction.

Herein, a tilt operation will be described with reference to FIGS. 4 and 5. The tilt operation is an operation using a tilt of the casing of the information processing apparatus 100 from a state of a time point as a reference. Herein, for example, as illustrated in FIG. 4, a reference point as a reference may be a time point of detecting a push operation of an operation body with respect to a display screen. When a user performs a push operation with respect to the information processing apparatus 100, the control unit 105 may detect a change in the tilt of the casing with respect to the state of the casing at this time point. Accordingly, the control unit 105 determines that a tilt angle is a tilted angle of the casing from the y direction with respect to the reference point. Herein, as illustrated in FIG. 5, a tilt operation in an ascending direction of the front side of the casing when viewed from the user is called a tilt up, and a tilt operation in a descending direction of the front side of the casing when viewed from the user is called a tilt down.

Next, a swing operation will be described with reference to FIG. 6. The swing operation is also an operation using a tilt of the casing of the information processing apparatus 100 from a state of a time point as a reference. Herein, a reference point may be, for example, a time point of the transition from a tilt operation to a swing operation. That is, the control unit 105 may determine that the reference point is a point of the conversion from a state with a tilt change with respect to the y direction to a state with a tilt change with respect to the x direction without a tilt change with respect to the y direction. Then, the control unit 105 may determine that a swing angle is a tilted angle of the casing from the x direction with respect to the reference point. When a swing angle changes, the control unit 105 may change a selection item display according to this swing angle. For example, herein, assume that a selection item C1-1, a selection item C1-2, and a selection item C1-3 are displayed before the change of a swing angle. In this case, when the user changes a swing angle, the display of the selection items C rotates such that the selection item C1-2, the selection item C1-3, and a selection item C1-4 are displayed. Herein, for example, the control unit 105 may select a selection item displayed in the center. The control unit 105 changes the selected selection item whenever the user changes the swing angle to change the display of the selection items C.

Herein, an example of a case where the present technology is applied to the selection of a selection item of a layered structure in a scene of selecting a content shift destination will be described with reference to FIG. 7. Herein, among the selection items illustrated in FIG. 3, the first layer is a layer for selecting whether a content shift destination is inside or outside the information processing apparatus 100 a. Also, herein, the selection items include a layer for selecting a content transmission destination device. The selection item 1 is “to transmit content to an external apparatus”, and the selection item 2 is “to add content in a playlist”. As illustrated in a display screen 301 of FIG. 7A, when in a state where a piece of content is selected and the operation body detecting unit 103 detects a push operation with respect to the content, the control unit 105 a displays a display screen 303 on which a header HID representing the selection item 1 and a playlist thumbnail group PT representing the selection item 2 are displayed. By this display screen 303, the user may know that he can perform an operation of selecting any one of the selection item 1 and the selection item 2. Also, in this state, when a tilt up operation is performed, it proceeds to FIG. 7B, and when a tilt down operation is performed, it proceeds to FIG. 7C.

First, a case where a tilt up operation is detected will be described with reference to FIG. 7B. When a tilt up operation is performed, a display screen 305 including a device base area DA for displaying a selection item of a transmission destination device is displayed. In addition, when a tilt angle is increased, the control unit 105 a displays a display screen 307 on which a device thumbnail DT is displayed on the device base area DA. Herein, the control unit 105 a may determine a display arrangement of the device thumbnail DT based on a frequency at which a selection item corresponding to each device thumbnail DT is selected. For example, the control unit 105 a may arrange a selection item with a high selection frequency at a position that is easily selected by the user. For example, the control unit 105 a may arrange a selection item with the highest selection frequency at the center. When a swing operation is performed on the display screen 307, a selection item represented by the device thumbnail DT rotates and simultaneously a selected selection item changes. Herein, the control unit 105 a selects the selection item corresponding to the device thumbnail DT displayed in the center. Also, in a state where any one of the selection items is selected, when a confirmation operation by an operation body is inputted, the control unit 105 a may confirm the selection of the selection item. Herein, when a drag operation with respect to a device thumbnail representing the selected selection item is detected, this selection (transmission destination device) is confirmed. Accordingly, the control unit 105 a transmits content to a confirmed transmission destination device CL1 through the communication unit 109.

On the other hand, a case where a tilt down operation is detected will be described with reference to FIG. 7C. When a tilt down operation is detected, the control unit 105 a determines a state where the selection item 2 further sliding in the playlist thumbnail group PT displayed on the display screen 303 is selected. Then, in the state where the selection item 2 is selected and a confirmation operation by the operation body is inputted, the control unit 105 a may confirm the selection of the selection item. Herein, when a drag operation toward the displayed playlist thumbnail group PT is performed, the control unit 105 a confirms the selection of the selection item 2 and adds the selection item 2 in a playlist.

In addition, when there are many selection items as illustrated in FIG. 8, the selection items may be displayed by being divided into a plurality of steps as illustrated in FIG. 9. When each layer corresponds to a degree of a tilt detected by the tilt detecting unit 101 and herein a tilt angle is within a predetermined first range, it becomes a state where a selection item corresponding to a device thumbnail displayed at the center among a device thumbnail group DTa is selected. Also, when the tilt angle is within a second range larger than the first range, it becomes a state where a selection item corresponding to a device thumbnail displayed at the center among a device thumbnail group DTb is selected. That is, the user uses a combination of a tilt angle and a swing operation in order to select a selection item of the second layer. In addition, the control unit 105 a may acquire a distance between the communication unit 109 and a transmission destination device represented by a device thumbnail, and may determine an arrangement of the device thumbnail displayed as a selection item, based on the distance. For example, the control unit 105 a may determine an arrangement of the device thumbnail so that the user can easily select a transmission destination device that is at a short distance. The control unit 105 a may select a smaller tilt angle as the distance from the transmission destination device becomes smaller. Also, the control unit 105 a may arrange a transmission destination device, which is at a short distance, in the center.

(Display Unit 107)

Returning again to FIG. 2, a description will be continued. The display unit 107 is an example of an output device, and may be a display device such as a liquid crystal display (LCD) device, an organic light emitting diode (OLED) display device, or the like. The display unit 107 may provide a display screen to the user under the control of the control unit 105.

(Communication Unit 109)

The communication unit 109 is a communication interface for allowing the information processing apparatus 100 to communicate with another apparatus. For example, the communication unit 109 may be a wireless communication interface for communicating with another apparatus by wireless. Specifically, the communication unit 109 may be an interface for connecting with a digital living network alliance (DLNA) compliant device by wireless. The information processing apparatus 100 a may function as a DLNA server, and may transmit content to a connected DLNA client.

[1-2. Example of Operation]

Next, an operation of an information processing apparatus according to the present embodiment will be described with reference to FIGS. 10 and 11. FIG. 10 is a flow chart illustrating an example of an operation in an operation of determining a content shift destination of the information processing apparatus according to the same embodiment. FIG. 11 is a flow chart illustrating an example of an operation at the time of arranging a device thumbnail according to a distance from a transmission destination device in the same embodiment.

Referring to FIG. 10, the control unit 105 a determines whether a push operation with respect to a moving image thumbnail MT is detected by the operation body detecting unit 103 (S101). If it is determined in step S101 that a push operation with respect to the moving image thumbnail MT is detected, the control unit 105 a slides out anything other than the moving image thumbnail MT (for example, a footer FT or the like) (S103). Then, the control unit 105 a slides in a header HD to an upper portion of a display screen, and slides in a playlist thumbnail group PT to a lower portion of the display screen (S105)

Next, the control unit 105 a determines whether a tilt up operation is detected by the tilt detecting unit 101 (S107). Then, if a tilt up operation is detected, the control unit 105 a displays a device thumbnail DT on an upper portion of the display screen and selects the transmission of content to an external apparatus (S109). After the device thumbnail DT is displayed, the control unit 105 a determines whether a swing operation is detected by the tilt detecting unit 101 (S111). Herein, if a swing operation is detected, the control unit 105 a rotates the device thumbnail DT according to a direction of the swing operation (S113).

The control unit 105 a changes a display position of the device thumbnail DT by the swing operation, and selects a device thumbnail DT displayed in the center among these. When any device thumbnail DT is selected in this manner, the control unit 105 a determines whether an upward drag operation, specifically a drag operation toward the selected device thumbnail DT, is detected by the operation body detecting unit 103 (S115). Herein, if a drag operation is detected, the control unit 105 a transfers a moving image to a device corresponding to a device thumbnail displayed in the center (selected) (S117).

On the other hand, if a tilt up operation is not detected in step S107, the control unit 105 a determines whether a tilt down operation is detected by the tilt detecting unit 101 (S119). Then, if it is determined in step S119 that a tilt down operation is detected, the control unit 105 a further slides in the playlist thumbnail group PT of a lower portion of the display screen and selects the addition of content in a playlist (S121). Then, the control unit 105 a determines whether a downward drag operation is detected by the operation body detecting unit 103 (S123). If a drag operation is detected in step S123, the control unit 105 a adds a moving image in the playlist (S125).

Also, if a swing operation is not detected in step S111, if a drag operation is not detected in step S115, if a tilt down operation is not detected in step S119, and if a drag operation is not detected in step S123, the control unit 105 a determines whether the detachment of a finger from the screen is detected by the operation body detecting unit 103 (S127). Then, if the detachment of a finger from the screen is detected, the control unit 105 a cancels the so-far process and ends the operation (S129).

[1-3. Example of Operation Using Tilt Degree (Example of Arranging Transmission Destination Device According to Distance)]

Also, when a device thumbnail DT is displayed in step S109 of FIG. 10, the control unit 105 a may determine an arrangement of the device thumbnail DT based on a distance from each device. An operation of the control unit 105 a in this case is illustrated in FIG. 11.

First, the control unit 105 a acquires a DLNA client list (S201). Then, the control unit 105 a acquires a distance from each DLNA client (S203). Next, the control unit 105 a determines an arrangement of the device thumbnail DT based on the acquired distance (S205). As described above, it may be preferable that this arrangement is made such that the user can easily select a device that is at a short distance. For example, it may be preferable that a smaller tilt angle may be selected as the distance becomes smaller. Also, for example, the arrangement may be made nearer to the center as the distance becomes smaller. Then, the control unit 105 a displays the device thumbnail DT in the determined arrangement (S207).

[1-4. Example of Display Screen]

Herein, it may be preferable that a display screen for selecting selection items of a layered structure is displayed three-dimensionally. A three-dimensional representational power may be used to improve an operability of the user. Herein, the respective objects displayed on a display screen are represented by a positional relation as illustrated in FIG. 12. FIG. 12 is an explanatory diagram for describing the arrangement of an object on a display screen displayed in the same embodiment.

Reference signs illustrated in FIG. 12 correspond to the reference signs illustrated in FIG. 7. For example, the moving image thumbnail MT corresponds to the object represented by the reference sign illustrated in the left diagram of FIG. 7A. In FIG. 12, according to the states, a moving image thumbnail MT1, a moving image thumbnail MT2, and a moving image thumbnail MT3 are illustrated. The moving image thumbnail MT2 represents an arrangement of the moving image thumbnail MT after performance of a push operation as illustrated in the right diagram of FIG. 7A, and the moving image thumbnail MT may be moved down by the push operation by the distance of a in a backward direction when viewed from the user. Also, when the moving image thumbnail MT is moved down, a footer FT1 is simultaneously slid out in a downward direction to become an arrangement of a footer FT2. Also, a background BG changes from a position of a background BG1 to a position of a background BG2. Also, instead of the footer FT, the playlist thumbnail group PT is slid in to become an arrangement of a playlist thumbnail group PT2. At this time, the header HD is arranged at the position of a header HD1.

Next, when a tilt operation is performed, the moving image thumbnail MT becomes an arrangement of a moving image thumbnail MT3 according to a tilt angle. Herein, along with the tilt operation, the device base DA is slid in from the upper side of a display screen. When a tilt angle increases, the device thumbnail DT is displayed on the device base DA. At this time, an arrangement of the device base DA is represented by a device base DA2, and an arrangement of the device thumbnail DT is represented by a device thumbnail DT2.

[1-5. Example of Effect]

The information processing apparatus 100 a according to the first embodiment of the present disclosure has been described above. In the present embodiment, the case of applying the technology of the present disclosure to a scene of transmission of content between devices corresponding to a DLNA has been described as a specific application example of the information processing apparatus that selects selection items of a layered structure by an operation of a plurality of steps using the detected tilt of the casing. According to the above configuration, the user performs a push operation of indicating content to be transmitted on the display screen with a finger, and may perform an operation of tilting (tilt up or tilt down) the casing without detaching the finger, thereby determining whether to move content to an external apparatus or perform an internal operation. Then, when the content is transmitted to the external apparatus, a transmission destination device may be selected by performing a swing operation using the tilt of the casing toward a further different direction.

Also, a drag operation or the like may be used to determine the selected selection item. An operation according to a tilt of the casing is intuitive, but may cause an erroneous operation if there is no feedback of a tilt degree. Therefore, a combination of separate operations by an operation body, such as a drag operation, may be used to reduce an erroneous operation.

<2. Second Embodiment (Generalized Example of Application)>

In the first embodiment, an example of applying the present technology in a specific situation where content is transmitted to an external apparatus has been described above. However, the present technology may be more widely applied to an information processing apparatus that selects a selection item of a layered structure. Therefore, the more generalized present technology will be described herein.

[2-1. Configuration Example]

First, a functional configuration of an information processing apparatus according to a second embodiment of the present disclosure will be described with reference to FIG. 13. FIG. 13 is a functional block diagram of an information processing apparatus according to a second embodiment of the present disclosure.

An information processing apparatus 100 b according to a second embodiment of the present disclosure mainly includes a tilt detecting unit 101, an operation body detecting unit 103, a control unit 105 b, and a display unit 107.

(Control Unit)

The control unit 105 b may select a selection item of a layered structure based on an operation of a plurality of steps using a tilt detected by the tilt detecting unit 101. The control unit 105 b may select a selection item of a first layer based on a first operation using a tilt with respect to a first direction. Also, when there is a selection item in a lower layer of the selection item selected by the first operation (second layer) among the selection items of the first layer, the control unit 105 b may display selection items of the second layer, and may select a selection item of the second layer based on a second operation using a tilt with respect to a second direction perpendicular to the first direction. Also, the control unit 105 b may confirm the selection of a selection item based on an input by an operation body detected by the operation body detecting unit 103.

[2-2. Example of Operation]

Next, an operation of an information processing apparatus according to the same embodiment will be described with reference to FIG. 14. FIG. 14 is a flow chart illustrating an example of an operation of a selection operation of a selection item of the information processing apparatus according to the same embodiment.

In addition, an operation described herein is a generalized one of the operation of the information processing apparatus 100 a described in the first embodiment, and the first embodiment is a specific example of the second embodiment.

First, the control unit 105 b determines whether a push operation is detected by the operation body detecting unit 103 (S301). Herein, if a push operation is detected, the control unit 105 b displays selection items of the first layer (S303). Then, the control unit 105 b determines whether a tilt operation is detected by the tilt detecting unit 101 (S305). Then, if it is determined in step S305 that a tilt operation is detected, the control unit 105 b selects a selection item of the first layer according to a tilt angle (S307).

Herein, the control unit 105 b determines whether there are selection items in a lower layer of the first layer (S309). If it is determined in step S309 that there are selection items in the lower layer, the control unit 105 b displays the selection items of the lower layer on the display unit 109 (S311). Then, in a state where the selection items of the lower layer are displayed, the control unit 105 b determines whether a swing operation is detected by the tilt detecting unit 101 (S313). Herein, if a swing operation is detected, the control unit 105 b selects a selection item according to the detected swing operation (S315). After a selection item is selected by step S315, or when it is determined in step S309 that there is no selection item in the lower layer, the control unit 105 b determines whether a drag operation is detected by the operation body detecting unit 103 (S317). Herein, if it is determined that a drag operation is detected, the control unit 105 b confirms the selection of a selection item based on the detected drag operation (S319).

As described above, according to the second embodiment of the present disclosure, the present technology may be applied in a case where a selection item of a more general layered structure is selected. For example, an example of a selection item of a layered structure may be a selection item in a screen that changes operation settings of the information processing apparatus 100 b. For example, among the selection items in the screen changing the operation settings, a selection item for changing display-related settings may be selected. For example, a selection item changing a display size, a selection item changing the brightness of a screen, or the like, may be present in a lower layer of the selected selection item. Herein, when the user selects the selection item changing a display size, a display size in a selection item of a further lower layer may be selected.

<3. Third Embodiment (Example of Application to Imaging Function)>

[3-1. Example of Configuration]

In the above-described second embodiment, a description has been given of applying the present technology when selecting a selection item of a more general layered structure. However, for example, other than the case of transmitting content to another apparatus in the first embodiment, the case of using an imaging function may be an example of the case where the application of the present technology is effective. Even when a touch sensor is used in an imaging apparatus, there is a strong need not to touch a display screen because the display screen is also a display screen displaying an image that is being captured. Therefore, it is also effective to apply an operation, which uses a tilt by the present technology, to a setting screen of an imaging function.

An information processing apparatus according to a third embodiment of the present disclosure will be described with reference to FIG. 15.

(Control Unit)

The control unit 105 c may further control an imaging function by the imaging unit 111. Also, a push operation or a drag operation used in the first embodiment and the second embodiment may be replaced with an operation by a hardware key in the present embodiment. When there is a strong need not to touch a display screen, if an operation by an operation body using a hardware key is used instead of an operation by an operation body using a touch sensor, it may be possible to prevent a fingerprint or a scratch from occurring on a display screen. The control unit 105 c may display, for example, a setting screen of an imaging function as illustrated in FIG. 16. Herein, as illustrated, when a longitudinal direction of a casing (y direction) lies sideways, a tilt operation is performed using a tilt with respect to a lateral direction (x direction).

The control unit 105 c may select any one of a selection item 21, a selection item 22, a selection item 23, and the like by a tilt operation. Also, when there is a selection item of a lower layer of the selection item 22 displayed in the center as illustrated in FIG. 16, the control unit 105 c may display a selection item 22-1 and a selection item 22-2 of the lower layer of the selection item 22. Also, the control unit 105 c may select any one of the selection item 22-1 and the selection item 22-2 by a swing operation. For example, the control unit 105 c may determine the selection of a selection item based on a determination operation by a hardware key.
